+ - CREATE TABLE ... SELECT. It is special, because only in this case,
+ the list of fields is allowed to have duplicates, as long as one of the
+ duplicates comes from the select list, and the other doesn't. For
+ example in
+
+ CREATE TABLE t1 (a int(5) NOT NUL) SELECT b+10 as a FROM t2;
+
+ the list in alter_info->create_list will have two fields `a`.
+
+ - ALTER TABLE, that creates a temporary table #sql-xxx, which will be later
+ renamed to replace the original table.
+
+ - ALTER TABLE as above, but which only modifies the frm file, it only
+ creates an frm file for the #sql-xxx, the table in the engine is not
+ created.
+
+ - Assisted discovery, CREATE TABLE statement without the table structure.
+
+ These situations are distinguished by the following "create table mode"
+ values, where a CREATE ... SELECT is denoted by any non-negative number
+ (which should be the number of fields in the SELECT ... part), and other
+ cases use constants as defined below.
